The present invention relates to a nozzle module capable of controlling discharge characteristics and, more specifically, to a nozzle module capable of controlling flow rate or discharge pressure through the adjustment of the length or the diameter of a nozzle. The nozzle module (10) comprises: a discharge module (2) including a discharge unit (21) which has a discharge path (211) for guiding a first fluid, and a guidance cap (22) which has a flow path (221) for guiding a second fluid; and a control module (1) including a needle piston (12) for controlling the opening/closing level of the discharge path (211) and a fluid supply unit (11) for supplying the second fluid. |
